To'aZZ whom it may concern:

Be it known that I, SHIMON FEIDMAN, a citizen of Russia, and residing at Petrograd, Russia, have invented certain new and use ful Improvements in Apparatus for. Packing Cigarettes, of which the following is a speci fication.

In machines constructed for filling cigarettes in. boxes in which a certain number of cigarettes is taken from alarge quantity of cigarettes, the defect occurs that the c1ga rettes are damaged when'being separated or when being packed, especially in the case when the cigarettes have to occupy two or more layers. This defect is due to the fact, that the quantity'of cigarettes in the hopper gradually varies and thus the whole massexerts an uneven pressure on the cigarettes which are being taken off from the bottom of the pile, and another defect resides in the arrangement between the hopper and the device which takesofl the cigarettes.

The present invention obviates these defects and provides novel means for separating a certain fixed quantity of cigarettes from a pile and for transferring the separated articles to the mechanism," which con ducts them into their box; I a e The accompanying drawings show by way of example one form of machine which embodies the present inve'ntiom'and' in which:

Figure 1 is a cross section through the hopper into which the cigarettes are charged, and the cigarette collecting device; 1

Fig. 2 is a side view as seen when looking in the direction of the arrow in Fig. 1 Y a r Fig. 3 isa plan view of the apparatus.

'Fig. .4 is a vertical section on the line A-B ofFig.3-. 'j' I Figs. Band 6 are section views on the lines CD and E-F of Fig. 4 respectively.

Figs. 7 and 8are sectio11al views on the lines G-H and KL of Fig. 3 respectively.

'Referring to the drawings and particu larly to Figs. 1, 2 and 3 thereof, the table of the machine is designated 2 and this table supports brackets 3 which carry the cigarette hopper 1. The hopper is of 'frustoconical shape and has an open top and are movable front cover (not shown in the draw ings). Located in the hopper is a divider'6 which separates the cigarettes into 'two streams and located beneath the divider are two inclined plates 4 and 5 whichseparate the lower portion of the hopper into two smaller hoppers. The cigarettes charged into the hopper fall by gravity past the dividing plate 6 and enter the small hoppers and the weight of the cigarettes on the lower cigarettes of the pile will be'formed' only by those cigarettes lying between the divider 6 and the bottoms of the smaller hoppers and thus an even pressure on the lower cigarettes is always insured.

Located beneath the hopper 1 is a shaking device 7 which is adaptedto be reciprocated by means of a lever 8 connected at'its upper end to one end of the shaking device by a pivot 9. The lever has a rocking movement about the axis 10 and is oscillated'by the cam 11.. In order that the shaking device shall be reciprocated in a substantially horizontal plane, its opposite end is connected by a pivot 12 with a link 13 rocking" about an vertical partitions are separated from each other by pockets 15*, which are of a thickness equal to the thickness of a cigarette.

The number of partitions in each traycorresponcl to the-number oi -cigarettes in each layer to be packed, forexample 10, 20 or more, Fig. 1 showing an example in wihi'ch 10 cigarettes form the bottom layerof each tray.

' Owing to the-small distance between the plate 6 andthe end walls'of the'hopper 1 and on account/of the small weight of the cigarettes, these latter fill both bottom halves of the hopper to a certain level, the height of which practically does not vary until all the cigarettes in the hop or arepacked. Whenjthe shaking device isat rest, the cigarettes from the hopper fall into the pockets-15 between the partitions in. the trays 15 and 16 and by periodically moving the shaking device 7 to andfro, the ciga rettes are caused to form layers in the trays 15 and 16. When at least one'cigarette 0ecupies each pocket of each tray, the layers formed thereby are then ready for the next operation.

According to the present invention, the cigarettes are pushed from the trays'not di rectly into boxes but into an intermediate member insuring the correct arrangement of the clgarettes in layers. Thls member consists of two open-ended channels 17 and 18 (Figs. 7 and 3), which are rigidly mounted on the table 2 in the rear of the trays and 16 and are arranged end to end with said trays,- so that when the latter are at'rest the I 21, which is mounted upon rollers 22- and 23,

the roller 23 being provided with a sprocket 23*, which is intermittently rotated by means of ratchet mechanism 24. I Each of the formers 20 have open ends and they are provided at their forward ends with inclined guides 20 which are horizontally slitted as shown at 20?. As the endless belt 21 is moved and the formers are brought into line with the channels 17 and 18, the walls of the slits 20 will engage the partition 19 and said partition will form a divider for the interiorof the two formers, which happen to rest end toend with the channels 17 and 18. In this manner alay'er of cigarettes carried by the channel 17 will be forced into the bottom of one former while alayer of cigarettes car-- ried the channel 18 will be forced into the upper ortionofan adjacent former and'as the en less belt moves beyond the plate 19 the two layers of. cigarettes occupying a former will come together.

In order to force the cigarettes from the trays 15 and 16,- through the channels 17 and 18 and into the formers 20, I have provided the pusher rods 25 and '26. These pusher rods are carried 'by a shoe 27, which is slid ably mounted in the table 2 and is recipro cated by means of a link 2 7?having one of its ends connected to the shoe and its other end pivotally connected to a lever 27"; The lever 27 rocks about an axis 27 and is oscillated by means of a cam 28, which is mount ed upon driving [shaft of the machine. The rods 25 are equal in number to the cigarett'es forming a layer and they are mounted at a lower level than the rods 26 in order that they may move through the pockets 15? of thetray 15 and force the lower layer of cigarettes from said pocket into the channel 17 and through said channel into the lower porticn of the particular former which rests with its end opposite the end of the channel 17. The rods 26, on the other hand, are mounted above the rods 25 and are adapted to force the lower layer of cigarettes from the tray 16 through the channellS and into the upper portion of the particular former,

Y which lies adjacent said channel.

.layers of cigarettes to be deposited in the trays 15 and 16. After a layer of cigarettes has been placed in each tray the shaker 7 is stopped and the pusher rods 25 and 26 then come into operation and move endw1se through the trays. The pushing rods 25 and 26 force the lower layers of cigarettes from the trays, through the channels 17 and 18 and into the formers which occupy positions directly in therear of the channels." It will be seen in this operation, that the layer from the channel 18 is deposited in the upper portion of one of the formers while the layer from the channel '17 is forced into'the lower portion of the other former, and that'in the next movement of the machine the former receiving the layer from'the channel 18 is moved forward one step in order to take the same out of alinement with said channel; The next former which received cigarettes from the channel 17 is moved into alinement with the channel 18, While afollowing former is moved into alinement with the channel 17 After two layers of cigarettes are placed in a former they are forced from the same into a package" by any ordinary means. 7 V

The present apparatus may be constructed so as to give not two, but three or even four layers of cigarettes, and to this end the pooh ets in the trays would necessarily have to 'be made deep enough to accommodate more than one layer of cigarettes. Itfis'also obvious that a greater number of cigarettes may be formed in layers by simply enlarging the length of the trays 15 and 16. V g.

Having now describedmy invention, what I claim as new and desire to secure by Letters Patent is f 1. Apparatus for the purpose described, coinprislng in combination,-. a cigarette containing hopper, oscillating trays beneath the mouth of the/hopper,- said trays being arranged at different levels,- an. intermediate member with fixed guiding channels each in line with a tray, formers adapted to receive layers of cigarettes, and means for transferring the cigarettes in the trays to the formers, whereby a bottom layer of cigarettes is formers adapted to contain layers of cigarettes, and means for transferring the cigarettes in the trays to the formers in such a Way that While into one of them a bottom layer of cigarettes is fed, an upper layer of cigarettes is fed into the other.

3. Apparatus for the purpose described, comprising in combination, a cigarette containing hopper, a double inclined plate spaced above the mouth thereof, whereby an approximately constant level of cigarettes in the mouth of the hopper is produced, oscillating trays beneath the mouth of the hopper, said trays being arranged at different levels, an intermediate member with fixed guiding channels each in line with a tray, formers adapted to contain layers of cigarettes, and means for transferring the cigarettes in the trays to the formers in such a way that While into one of them a bottom layer of cigarettes is fed, an upper layer of cigarettes is fed into the other.

fl. In acigarette packing machine the combination with a hopper adapted to contain the cigarettes to be packed, of a shaking device located beneath said hopper and carrying a plurality of trays arranged at different levels, channels arranged adjacent one end of said trays, said channels being arranged in planes corresponding to the levels of the trays, a plate extending across said channels and forming the top of the lowest channel and the bottom of a rality of formers arranged adjacent said channels and having slotted portions in which said plate rests for dividing the interiors of the formers into a plurality of chambers, and pushing devices adapted to force layers of cigarettes from said trays, through said channels and into said formers.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
